Should entities have behavior? or not?

If your entities do not have behavior, then you are not writing object-oriented code. If everything is done with getters and setters and no other behavior, you’re writing procedural code.
A lot of shops say they’re practicing SOA when they keep their entities dumb. Their justification is that the data structure rarely changes, but the business logic does. This is a fallacy. There are plenty of patterns to deal with this problem, and they don’t involve reducing everything to bags of getters and setters.
